Answer:

the product of 5 and a number

Step-by-step explanation:

$5n$ is really $5 * n$ .

In higher education math, the multiplication sign is not used. A number and a variable (or a equation in grouping symbols) would be just together next to each other. When it's like this, you would have to multiply the numbers.

Example:

$4n; n = 2\\4(2) = 4* 2 = 8$

Answer:

v is negative for every x, meaning the domain is all values in R, whatever goes under the squared sign will come out as positive and the left out -ve sign will make V negative for all x in R

range of f(x) is -inf to +inf

Step-by-step explanation:

the cubic power doesnt affect the sign

An angle measures 8.8° more than the measure of its complementary angle. What is the measure of each angle?

Fittoniya [83]

Based on the definition of complementary angles, the two angles are: 49.4° and 40.6°.

<h3>What are Complementary Angles?</h3>

Angles that are complementary angles have a sum of 90 degrees.

Let the angle be represented as x

Complement of the angle = (90 - x)

Therefore, we would have:

x = (90 - x) + 8.8

x = 90 - x + 8.8

x = 98.8 - x

x + x = 98.8

2x = 98.8

x = 98.8/2

x = 49.4°

The second angle would be: 90 - 49.4 = 40.6°

The angles are 49.4° and 40.6°.
